Interstitial filtration and collection device and method for long-term monitoring of physiological constituents of the body

摘要: An implantable filtration and collection device for collecting a filtrate containing physiological constituent of the body present in an interstitial space. The is operable with negative pressure generating source to withdraw from includes porous filter made material compatible long-term patency inside adapted be implanted fluid communication pores are sized not exceed predetermined dimension corresponding size being filtered. A collector form elongate tube connected serves communicate externally where it may withdrawn by source.
